如何在 Django Rest Framework 中通过电子邮件发送动态数据

Question

我正在尝试编写一个在文件上传后发送通知电子邮件的函数。如果我对 "send-to" 电子邮件地址进行硬编码，则我的以下代码有效。

def perform_create(self, serializer):
        serializer.save(owner=self.request.user)
        from_email = self.request.user.email
        send_mail('New Files have been Uploaded',
                  'New files have been uploaded.',
                  from_email,
                  ['sendto@email.com', ],
                  fail_silently=False)

我需要根据序列化程序中的 editor_email 动态设置 "sendto@email.com"。下面是序列化程序。

class VideoSerializer(serializers.ModelSerializer):
    projectName = serializers.SerializerMethodField(allow_null=True)
    editor_email = serializers.EmailField(
        source='editor.email', required=False)

    class Meta:
        model = Video
        # fields = '__all__'
        fields = [
            'url',
            'handle',
            'filename',
            'size',
            'source',
            'uploadId',
            'originalPath',
            'owner',
            'project',
            'uploadDate',
            'editor',
            'projectName',
            'editor_email'
        ]

    def get_projectName(self, obj):
        return obj.project.projectName

当我检查应用程序前端的 JSON 响应时，"editor_email" 的值是我期望的值。

我对 Django Rest Framework 比较陌生，这里一定有我遗漏的东西。我花了几个小时阅读文档并尝试不同的方法，但似乎没有任何效果。

拜托，有人可以告诉我如何根据序列化程序设置此电子邮件吗？

从 views.py 中删除邮件发送代码片段并将其移动到 serilizers 中作为

# views.py
def perform_create(self, serializer):
    serializer.save(owner=self.request.user)
    <b><strike>from_email = self.request.user.email
    send_mail('New Files have been Uploaded',
              'New files have been uploaded.',
              from_email,
              ['sendto@email.com', ],
              fail_silently=False)</strike></b>


# serializers.py
class VideoSerializer(serializers.ModelSerializer):
    # your code


    <b>def send_dynamic_mail(self, video_instance):
        from_email = video_instance.owner.email
        send_mail('New Files have been Uploaded',
                  'New files have been uploaded.',
                  from_email,
                  [video_instance.editor.email, ],
                  fail_silently=False)

    def create(self, validated_data):
        video_instance = super().create(validated_data)
        self.send_dynamic_mail(video_instance)
        return video_instance</b>

我认为您可以在函数中获取字段 editor_email 数据。如果它只是字符串数据，那么你可以这样做：

def perform_create(self, serializer):
        serializer.save(owner=self.request.user)
        to_email = serializer.data['editor_email']

        if to_email:
            from_email = self.request.user.email
            send_mail('New Files have been Uploaded',
                      'New files have been uploaded.',
                      from_email,
                      [to_email, ],
                      fail_silently=False)
